BOTTLE-STOPPER.

Patented May 26,' 1 908.

To all whom it may concern.

Be it'known that I, GEORG KIRKEGAARD,

a citizen of the United States, residing at the city of New York,'in theborough of Brook- 5 lyn and State of New York, have invented certain newand useful Improvements in Bottle- Stoppers, of which the following is afull, clear, and exact description.

This invention relates to Stoppers for that type which comprises ametallic cap with means for engaging an annular shoulder on theexteriorof the neck of the lbottle to hold under compression a'packingdisk interposed between the mouth of the bottle and the cap.

The object ofthe invention is tolprovide means for holding the cap .onthe bottle against the internal pressure which for its efficiencydepends upon the shape or formation of the metallic portion of the caprather than upon the stiffness or weight of the metal of which the cap.is composed; I am thus able to use a comparatively thin metal for thecap and achieve a corresponding economy in the manufacture thereof.

A further object of the invention is to provide a construction whichwill aid in the removal of the stopper from the bottle.

My improved construction is illustrated in the accompanying drawing, inwhich Figure V1 is a side elevation of the cap or stopperfbefore it isapplied to the bottle; Fig.

2 is a lan of the same looking at its under side; ig. 3 is asection online -:v of Fig. 2; Fig. 4 is a section on the line y-y of Fig. 2; Fig.5 is a section of the cap applied to the bottle and Fig. 6 isa sideelevation of the sto per showing a removing device.

he cap com rises essentially a disk 1, hav ing integrally ormed with ita vertical depending wall 2, and a flaring rim 3 dependmg from thevertical wall. The cap contains the usual disk of packing material 4,such. as cork or aper, which is to be com ressed against the mouth ofthe bottle .to e ect the seal. This cap is adapted to be applied to thecommon form of bottle having an eXterior annular inwardly inclinedshoulder 5, to be engaged b the holding devices on thecap. The saidholrding devices of my improved cap are formed upon the flaring rim 3.For this purpose the shape ofthe rim is not flat like a zone from acone, but is curved like a bottles, jars and similar receptacles,`and isof zone from a dome. It is provided with a series of inwardly andupwardly bent lips 6, each being formed by bending a short length ofthel edge of the rim inward and upward, leaving short vintermediateportions of the Vextreme edge unbent, as indlcated at 7, into which thebeIit-up lips merge. 'The lips are thus reinforced by their connectionwith the extreme edge of the rim;

forced downward thereon until the cork is compressed so that the upperedge of the lips will fall within the zone of the shoulder 5. Then byforcing the rim 3 inward to the osition shown in Fig. 5, the upper edgesof) the lips will be forced against the shoulder 5 and hold the cap onthel bottle with the cork under compression. The strength of this holdis rest with their edges against the shoulder 5 taper downintoconnection with'the eXtreme unfolding or bending downward, and theresistance'of the cross-section of the metal is obtained to prevent thestopper Afrom becoming forced from the bottle.l The machine or tool forapplying this cap to the bottle will be very simple, since it willrequire only the p lunger to press on the top of the cap and a simplering passed down on the outside of the vertical wall 2 and forcedinvFvard on the rim 3 to thel position .shown in In Fig. 6 I have shownan improved form of device for facilitating the removal of the cap fromthe bottle. Various forms of handle have been vheretofore proposed whichhave been in the form of a strip depending graspedy in the hand to liftone' side of the stopper and thus free it. But where the 'stopper ismade of very thin or light metal, as 1s possible in the constructionhereinabove described, the simple tail piece is impracticable forhandling, since it merely bends and does not afford any leverage to freethe cap. Therefore I ypropose vroviding the tail piece 8, which is madea ittle Wider than usual, with an eye or opening 9, in which any tool,

inserted and used to pull the stopper. from the bottle, the thin metalused belng amply strong to stand the force necessary to be eX- erted forthis purpose.

from the edge of the cap and intended to bel When the cap is applied toIthe bottle, it is i increased from the fact that the lips which edge at7. Thus the lips are prevented from such as a fork, button hook or anail, can be 1 05.

Having now described my invention, what I claim, 1s:-

1. A bottle stopper comprising a metallic cap containing a packing diskand having a depending ange provided with a plurality of inwardly andupwardly turned lips merging at their extremities into the eXtreme edgeof the flange.

2. A bottle stopper comprising a metallic cap having a packlng disktherein and having a vertical side Wall and a flaring rim or edgeprojecting therefrom, said rim or edge having a series of inwardly andupwardly turned lips, the ends of which n'lerge into the extreme edge ofthe flaring rim, for the purpose set forth.

In witness whereof, l subscribe my signa-` ture, in the presence of twowitnesses.
